Alemar Dam dam
Alemar Dam
Alemar Dam, located in Isle of Wight, Virginia, is a crucial water resource infrastructure primarily used for irrigation purposes. Managed by the Department of Conservation and Recreation, this earth-type dam stands at a height of 17 feet and has a storage capacity of 69 acre-feet. The dam is situated on the TR-Beaver Dam Swamp, within the jurisdiction of the state, where it is regulated, permitted, inspected, and enforced for safety and compliance.
Despite its importance for water management in the region, the condition of Alemar Dam is currently not rated, and its hazard potential is undetermined. Emergency action plans and risk management measures are yet to be fully developed and implemented for the dam. While it has not undergone recent inspections or assessments, the dam remains a critical structure for irrigation and water supply, highlighting the need for ongoing monitoring and maintenance to ensure its safety and functionality for the surrounding community.
In the absence of a comprehensive risk assessment and emergency preparedness plan, stakeholders and officials must prioritize the evaluation and management of Alemar Dam to mitigate potential hazards and ensure the continued reliability of this essential water resource infrastructure. Proactive measures, such as regular inspections, condition assessments, and the development of emergency response protocols, are necessary to safeguard the dam and the water supply it provides to the area. Collaboration between state agencies, regulators, and local authorities is crucial to address any potential risks and enhance the resilience of Alemar Dam in the face of changing climate conditions and water resource demands.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Alemar Dam
Where does the data for Alemar Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Undetermined hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
